ANC system installed in cars and hearings aids

Hello everyone.

I am gonna ask a question which intrigue me so much - maybe some people out there have some knowledge about this topic and can help me understand it. How the hearing aids behave in the car which has an ANC system installed inside? The Active Noice Cancelling system creates the exact opposite of the soundwave that was recognized as the noise and sends it to the car audio system. Can these opposite soundwaves be, for an example, recognized as the whistle or noise by the hearing aid microphones? I used to look for a car with an ANC system but I have no clear answer to my question and in result some car models are questionable for me at this point.

Thank you so much for your answers in advance :smiley:
